Which term describes the area between nodes on a stem?

• A. Internode
• B. Cotyledon
• C. Plumule
• D. Seed coat

Answer: (A)

In plant anatomy, the area between nodes on a stem is called an internode. Nodes are the points where leaves attach and buds form, so the internode is simply the stem section between those attachment points. This term matters in landscape management because internode length affects plant height and spacing—longer internodes mean taller, more leggy growth, while shorter internodes produce a more compact form. Cotyledon refers to the seed leaf that appears during germination, not a stem segment. Plumule is the embryonic shoot inside the seed that will develop into the above-ground part of the plant, not the space on the stem. Seed coat is the protective outer layer of the seed, not part of the stem structure.
